The requirement for filter efficiency measurement (contamination control) has been outlined for years by ASHRAE 52.1 as a classical gravimetric method. Since the concentration of smaller particulate in ambient air is dramatically increasing, new methods need to be developed for air cleaning devices to study the removal efficiency by particle size. ...

The NUCON Model AGT is a high-output portable thermal aerosol (DOP or PAO) generator. It can provide up to 241 mL/min of submicron PAO, or 121 mL/min of submicron DOP, aerosol. System pressure indicator and all operational controls are on the front panel. Liquid to gas phase conversion takes place in a continuous stainless steel coil cast in an ...

Aerosol Generator 3079 is a rugged, compact atomizer generates particles in concentrations up to 108 particles/cm3 and offers an adjustable flow rate from 1.0 to 4.2 L/min. A built-in, low-noise compressor provides compressed air, and the atomizer head is made entirely of stainless steel. Operating components are protected by a hood, making this ...

The Aerosol Monitor which has easy-to-read display, and link to Ethernet system, can materialize simplified monitoring of Particulates at multiple location. It's the perfect for monitoring any place where you need simplified cleanliness level monitoring, such as the gowning area of a cleanroom.The monitor provides stable and sensitive detection ...

Generation of test aerosols from powders, pollen, and biological agents, mass flow approx. 40 mg/h – 430 g/h. Low-concentration solid particle aerosols produced from powders are required for many applications in research, development, and quality assurance and for the calibration of particle measurement devices. For more than 25 years, the ...

The Aurora 4000 polar nephelometer is the only commercially available polar nephelometer in the world. The polar nephelometer goes beyond simple integrated nephelometers and allows much more detailed measurements. The Aurora 4000 polar nephelometer uses a programmable backscatter shutter which allows the user to set up to 17 customisable angles ...

Easy to use and maintain, the Aurora 1000 lowers the cost of ownership for aerosol light scattering, visibility and particulate monitoring instrumentation. The Aurora 1000 uses a single wavelength LED for light scattering coefficient and visibility measurements. Ecotech, through collaboration with globally renowned atmospheric research institutes, ...
